Lambda Functions

Have you ever tried to do something with CloudFormation but just needed a little something more to get the job done? In those cases I’ve started using CloudFormation custom resources. These resources essentially allow you to extend the use of CloudFormation templates whenever you create, update or delete a stack.

In this tutorial, I’ll show you how you could use these custom resources to provision your DynamoDB tables with some data. This can be useful if you’d like to run additional testing on your AWS environment that requires actual data inside of the environment.
